The smart UV choice for ponds, water gardens and water features up to 2,900 gallons. Emperor Aquatics SMART Lite Pond UV Clarifiers boast signature SMART UV design for optimized UV performance. Heavy-duty UVs deliver maximum clarifying UV-C output through careful positioning of the UV lamp. Long-lasting UV lamps are positioned entirely between the inlet/outlet ports so the entire length of the lamp is utilized. The result is optimum protection against water borne, green water algae for crystal clear pond water.

Quartz Sleeve
Please Note: A water test should be performed each time the quartz sleeve or gaskets and O-rings are replaced (once annually). Performing a water test will determine whether or not a proper seal has been achieved. Failure to achieve a proper seal during SMART UV operation will allow water to leak into the inside of the quartz sleeve, potentially damaging the UV lamp and other electrical components, which could develop into dangerous situations.

Installation
SMART UVs require no additional hardware for wet applications. Regardless of the application, solid waste should be removed from the water before it enters the UV Clarifier. Proper installation improves performance, longevity and safety. Install SMART UVs where they can be easily serviced.

Do not operate the UV Clarifier with a new installation containing fish until the water has been tested, showing that the nitrification cycle has been completed and biologically balanced.

External or Submersible Pump Installation
Match the SMART UV capacity to the re-circulating flow rate performance of the pump. Installing a check valve after the UV Clarifier will eliminate back-siphoning. Installing true-union ball valves will allow flow adjustments and UV Sterilizer removal. For best results, install a saddle-style water flow meter, mounted horizontally on the outlet side of the UV Clarifier. Follow the water flow meter manufacturer's instructions for proper installation and operation.

External or Submersible Pump Installation w/ by-pass manifold
This installation configuration is identical to the External or Submersible Pump Installation but with the addition of a bypass manifold. The bypass is used to deliver a precise water flow to the SMART UV Clarifier when the overall clean water return flow rate exceeds the UV's capacity.

Follow the water flow meter manufacturer's instructions for proper installation and operation.

Quartz Sleeve Cleaning:
It is recommended that the UV quartz sleeve be visually checked for cleaning once every three months of operation. Be aware that even the slightest layer of material (slim/dirt) coated on the outside of the quartz sleeve can have a profound effect on UV-C light transmittance through the glass and into the water. Cleaning frequency is dependent on how well you are filtering the water (solids removal) prior to the UV.

To clean the quartz sleeve:
Unplug the UV and shut the water pump off. Next, unthread the UV's black retaining nut and gently remove the quartz sleeve assembly and lamp from the UV housing. Inspect the quartz sleeve and clean as needed with a soft, clean cloth. For calcium deposits, use vinegar or muriatic acid to dissolve/clean. Be sure to remove any cleaners or acid before reassembling the quartz sleeve assembly and lamp back into the UV housing.

Incorporate UV sterilizers as an invaluable tool in an algae control regimen in your pond. As water flows through the UV unit, free-floating algae are exposed to ultraviolet light and flocculate. Find out how this helps control algae.
